Application filed lune 7, 1919. Serial No. 302,421.

To all whom t may concern:

Be it known that l, JOHN G. EKLUND, a citizen of the United States, residing at St. Joseph, in the county of Berrien and State of Michigan, have invented a new and useful Basket-Cover-Stitching Machine, of which the following is a specification.

This invention has reference to machines for making hoop covers for stave bushel baskets, and its object is to provide a machine whereby the covers may be made of staves and a joining hoop irmly stapled together with the staples all properly positioned with reference to the hoop so as to enter the material of the hoop at a predetermined distance from the outer margin there of so that all staples will be embedded in the hoop.

A. basket hoop is made of relatively thin material bent upon itself into hoop form with the ends joined by overlapping in the usual manner. With such a hoop there is not only variation in the circular' contour but in the thickness of the stock. For these reasons it frequently happens that the staples employed to secure the staves onto the hoop may entirely miss the hoop and therefore have the points exposed where they may do harm to the person handlingr the covers or in other manner.

ln accordance with the invention the hoop is mounted upon a rotatable carrier and the stapling head is held in a certain relation tothehoop so mounted that the staples will enter the hoop aboutmidway of its thickness and consequently find a backing of wood. This is accomplished by controlling the stitching or stapling mechanism in such manner that it has imparted to it a normal tendency toward the hoop and holds the position so determined, with respect to the hoop, while the stitching mechanism and hoop are maintained in the determined relative position until the stitching or stapling is completed, wherefore, the staples will be` driven into the hoop not only in spaced relation to each other but in constant spaced relation to the outer edge of the hoop. By such means the staples are always driven into the wood of the hoop and no staple points are exposed, nor is there liability of splitting the hoop as mightoccur if the staples varied in distance from the edge portion of the hoop.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the show` ing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings z,

Figure 1 is an elevation of a portion of a stitching or stapling machine equipped with the invention.

Fig. 2 is a plan view ofthe structure shown in Fig. 1, but omitting distant parts.

Referring to the drawings, there is shown a post 1 which may be considered as the post or standard. of a known form of stapling machine. Journaled on the post is a shaft 2 provided with an elongated journal bearing 3 carried by a bracket l fast to the post. The shaft 2 is provided with a sprocket wheel 5 and a ratchet or lock wheel 6 where by the shaft 2 may be given a step-by-step forward movement. At the end of the shaft 2 remote from the sprocket wheel 5 it has fast to it a bevel gear wheel 7 meshing with. another bevel gear wheel 8 carried by an upright shaft; 9 extending through a jour nal bearing 10, in turn carried by a prolongation 11 of the bracket t. The upper end of thc shaft 9 has fast to it a turntable 12 having a marginal exterior ledge or flange 13 designed to receive and support a hoop 1li, which hoop may` consist of an ordinary basket hoop needing no particular description. It is the purpose of the machine to secure staves 15 in suitably spaced relation to the hoop 14 so as to produce a cover of any suitable size, say stave bushel basket size, although the invention is not necessarily confined to such particular size of container'. The cover is provided with a cross piece 16 at right angles to the staves 15 so as to not only stiften the cover but provide a convenient handling means therefor.

Mounted on the post 1 is a head 17 carrying the basic portion 18 of an oscillatory stapling head 19, which latter may be of approved pattern and needs no particular description. The stapling head is of a character whereby staples, such as shown at 20 in Fig." 2, may be driven at determined intervals through the staves 15 where overlying the'hoop 14 so that the staves are properly secured to the hoop. The -stapling head so mounted that it may be swung over the turn-table 12 or away therefrom and when over the turn-table is then so located that the staples are driven through the staves into the hoop between the side walls ot the hoop and at a certain distance from the outer wall.

The basic Vportion 1S of the stapling head 19 carries an arm 21 to which is secured one end of a spring 22, the other end of the spring being made tast to a bracket secured to the upper tace` ot the head 17, so that the base 18 may move about an upright aXis, with the spring 22 tending at all times to move the stapling end of the headl 19 to- .ward the'turn-table 12. The arm 21 is shown in Fig. 2 as in radial relation to the axis et oscillation of the base 18 and in the path et the arm 21 is one end of a spring 24 tast to the upper face of the head 17. The spring or catch 24 is a leaf spring and its free end is formed' with a notch or depression 25'so arranged that the arm 21 will snapinto the depression, thereby holding the stapling head in the inactive position but in such manner that the stapling head may be readily released by hand, whereupon the spring 22 will move the stapling head into active position. To determine such active position the staplingheadhas a. bracket 26 fast to and Vcarried thereby and on this bracket is mounted 4`a roller 27er round-nosed piece ot steelor other suit-able gage means so positioned as to bear against the outer edge of a hoop 14 when mounted on the turn-table 12. Carried by a comparatively rigid part ot the -machine is an anvil 28, shown in Fig. 1 as supported by a bracket 29 on liXed parts of the machine. Thefanvil 28 is adjustable up and down by being provided with a screw stem 30 and a lock nut 30 but may be otherwise constructed, the purpose of the anvil being Itoprovide an under support tor that part ofthe table A12 over which the staple, part offthe stapling head is located. Inv order to aid in the manipulation ot the stapling head there is provided a handle so situated as to be in ready reach of an operator, so that the .-stapling head may be moved out of operative position when it is desired to place a cover in position for stapling or to 4remove a inished cover. The roller 27 takes careY of the proper placing ot thestaples with respect yto the axis. of rotation Aof the cover while the machine automatically spaces the staples with respect te the ,stavescircumterentially of the head and drives them.

It is .to-be understood that the invention is applicable to .that type of stitching machines for making hoop covers for stave bushel baskets in which the turn-table is capable of oscillating toward and from the stitching` head which is then held against such oscillatory movements, a-nd in the claims the statement that the table and stapling head are relatively movable, is intended to be broad enough to cover either type o1 machine.
